Abstract

Compositionally modulated crystals of the superconductor Ba_1-x K_xBiO₃ have been grown electrochemically. Modulation was produced through control of the deposition potential.

Modulated crystals were imaged using optical microscopy, backscattered SEM, and STM. The expected linear relationship between the amount of time that current was applied and the modulation thickness was observed, and the growth rates were determined.

Multilayers were differentially etched using an EDTA solution. Etched and unetched samples were imaged using backscattered SEM.

The transition temperature of a modulated sample was determined by SQUID magnetometry to equal the bulk value.
